' veniently transferred -from oneenced-,field to another without disconnecting saine from the draw bar or the draft means to which the draw bar is attached. o

A further purposevof the-'invention is to provide a variable ylength draw bar adjust- ',able to suit implements ot 'varying Width and having novel means for ,securing4 rela-L tively movable sections [ofthe draw bar in adjusted position.v j Y A still urtherpurpose of the invention is Ato provide novel means for securing the dranT bar to the draft means andto aseotional implement in such manner that the length ot the draw bar can be conveniently reduced and certain sections of the imple-` ment partly or wholly detached from p0rtions of the drawbar and placed upon the` remaining` sections ofthe'implement so as to permit the draw bar and implement to be conveniently drawn through a gateway of ordinary width. l

Other purposes and advantages of the invention as well as the details of construction and arrangement of parts constituting the preferred embodiment herein disclosed Awill be more readily understood from the tollow- :ing detaileddescription and accompanying drawings in which, i

Figure 1 is a top plan view of my iinproved draw bar connected to a vsectional harrow the sections oit which are indicated by dotted lines.

Proceeding now to a more detailed discustion of the drawings 5 designates a draw bar consisting of the hollowy tubular sections 6,

7 and 8, the central section 6 beingmade ot sullicient diameter toL telescopically receive therein the inner ends of the outer sections 2 is a fragmentary longitudinal H t .M l .i v' v l and 8 wherebysaid outer sections maybe projected or retrac'tedwith respect to the i l central sectionl to vary they ell'ectivevlength Y of the draw banV a I The severalvsections of secured in adjusted. position by lock pins 9 the draw barbare n passed through registering (iipeiiingsV 10 and.

11 formed respectively in the central section 6 andthe outer sections 7 and S. Preferably,

therentral section 6 is provided `with a sin-rA ygle-open1ng,10;,at each end while the outer,`

sections are provided with a series of openings 11 adapted to be selectively aligned with thejopenings 10in effecting the various adjustments of the-sections. In order to yprev-,ent accidental displacementthereof each lock pin-9 is yflattened atan intermediate pointy to provide projecting side wings12` i `and 13 which, during insertion of the pin,

are received through the lateral extensions f 10 of the openings 10 and the lateral eX- tensions 11., oit the upper openings 11 of the outer sections 7 and 8. After the wings 12 and 13 yof the pins have been passed through the last mentioned openings 10 and 11 to ydispose the'flattened portions otv the: pins wholly within the outer sections 7 andA Sthe pins are turned axially tor dispose the wings 12 and 13 between and at right angles to the aforesaid extensions 10 -and 11 whereby the uppery terminals of the wings abut the inner upper surfaces of the sections 7 and 8 f said openings to prevent displacement of the pins.rk Preferablythey pins/are bent at the'uppcr ends to form heads 14 arranged to frictionally grip? the at opposite `sides of central section Gdui'in'g the aforesaid turn@ ing of the pins. 4 o f j In the present instance I have shown the draw bar as adapted for use in connection with a harrow of the multiple frame or unit type and provision is made as follows for Yconnecting the draw bar to the draft means and to the units of the barrow. Each ot the sections 7 and 8 of the draw bar is equipped at its outer end with a clamp 16 consisting of two plates receiving said sec-Jr tions therebetween and terminally secured together by bolts 17 and 18. The bolts 17 are attached by link connectionsy 19 toa draft ring 2O which inturn is attached to the draftmeans (not shown). The bolts 18 are connected by chains 21 or other flexible connections to the outer eyes 22 of the terminal. kliairow trames 23. These trames are also equipped with inner eyes 24 attached by chains or other flexible connections 25 to the bolts 26 ot' clamps 27 carried by the outer ends of the central section 6.` InWardly of the clamp 27 section 6 is provided with additional clamps 2S corresponding exactlyin structure rto the first mentioned clamps 1G and including terminal securing' bolts 29 and 30, the bolts 29 beingconnected by link means 3l to the draft ring 20 `and the bolts 80 being-connected by chain or flexible connections 32 to the outer eyes 33 of the intermediate barrow sections 34 and 35, the latter being both provided with inner eyes 36 connected by chainsor flexible connections`37 to clan'lps 38 encircling the intermediate portion ot section 6.

lVith the `arrangement described in the foreo'oino' it is manifest that the lenOth oiE D D 23 the draw 'bar and the 'Width ot' the hai-row may be conveniently reduced byV detachingl the connections 2l between the `draw bar sections `7 and 8 and the outer harroW sections 23 and swinging the latter inwardly to lie upon-the"intermediate liarrovv sections 34 and 35y subsequent to which the lock pins 9 may be removed to permit the outer `draw barV sections 7 and 8 to be retracted within the sections 6 to the ententnecessary thereby enabling* vthe required adjustments to be `made `Without completely disconnecting the barrow from the draw bar or the draw bar from the draft means.

In lieu ot'tliearrangen'ient ot clamps described in the foregoing it will be understood that the ilegible `connections `to the Adraft ring `and tothe barrow sections or other j implementsv that may be substituted therefor may be Welded or otherwise directly secured tothe sections of the draw bar.

Inadaptmg' the draw bar tor use With implements ot 1varying Width it Will be understood that the sections 6,7 and 8 are ad- Ijusted to give the desired length ofdraw bar andthen secured in adjusted position by apsignature.

plying the lock pins 9 as previously explainech Having thus fully described What I now conceive to be the preferred embodiment of my invention it will be understood that various changes maybe resorted to within the scope of the appended claim and that the dranY bar While shown in connection with a barrow is not limited to such application but may be" applied to any otherimplement to Which it may be adapted Within the spirit ofllthe invention as herein defined.

That I claim is: y

A longitudinally adjustable draw bar com prisii'ig ahollow intermediate section, outer sections slidably mounted within the inter mediate Vsections and capable oitlbeing proj ectedor retracted with respect to vsaid intermediate section to thereby vary the effecttive length o't'the draw bar, means `for se# curing said sections togetherinany selected `positionV of relative adjustment, a pair of spaced clamps'encircling the `central portion ot' theintermediate section and formed to provide for the attachment of barrow units thereto, a further pair of clamps encircling the intermediate sectionl adjacent the outer ends ot said section7 each of said clamps being provided at the iront side of the d aw bar With meansvfor attaching the saine to a draft appliance and `at the rear side of the draw bar with'means 'or attaching the same `to the aforesaid harrow units and additional clamps carried by the extreme outer ends of the intermediate section and by the'outer ends ot the outer sections `and atl'ording a means for the attachment ot further barrow units, the clamps carried by the Outer ends l of the outer sections being provided at the front side of the draw bar With fmeans for attaching` same to the draft appliance.
